We've looked at travel systems and if we buy brand new would go for the Mamas and Papas Zoom system but we've been looking at ebay etc too. Obviously we wouldn't buy a second hand car seat but when we started finding good pram/pushchair alternatives on ebay I found myself becoming all pfb! I'm now not so sure about the idea of it being used by a strangers baby etc - can you steam clean them? Does the SIDS risk/guidelines apply to carry cot mattresses too? Am I being really silly here (I think I know the answer though!!!).
